This article reviews the literature on the economics of farm animal welfare. It starts with the challenge of defining and measuring animal welfare. Subsequently, the demand for farm animal welfare is evaluated from both the citizens’ perspective and the consumers’ perspective. The much-cited preference gap in between these perspectives constitutes a dilemma for the governance of animal welfare. Literature on the supply of farm animal welfare discusses the implications of enhancing farm animal welfare for production cost. The linkages between farm structure, farm technology, and animal welfare are discussed, and the frequently voiced hypothesis that smaller and more traditional farms automatically imply higher farm animal welfare levels is rejected. We examine the central challenge to the governance of farm animal welfare: its effects on competitiveness and trade. We also discuss objectives, governance instruments, the interplay of different policy instruments, and how to combine them for an effective and efficient strategy for farm animal welfare.

Abstract This article reviews ways of representing the effects of decoupling in the European Union (EU) on land allocation and production in eight selected simulation models (AGLINK, AG‐MEMOD, CAPRI, CAPSIM, ESIM, FAPRI, GOAL and GTAP). It then compares the simulated effects of decoupling and traces them back to the model specifications and parameter assumptions. In particular, roughage is not included in most models, so that changes in ruminant production are not necessarily consistent with the changes in fodder area. Models also differ in the extent to which they reflect the substitution possibilities in ruminant feeds. Notwithstanding the considerable differences in model types and specifications, all the studies considered here predict that as a result of decoupling, areas allocated to cereals (and silage maize) and beef and sheep production in the EU‐15 will decline, while fodder area will increase. Differences in the projections about pasture, oilseed and set‐aside areas can be attributed to different model or scenario specifications. The most important factor affecting the results is the extent to which the models assume that the Common Agricultural Policy (CAP) 2003 Reform (regarding Single Farm Payments) involves a substantial decoupling of support compared with the baseline (Agenda 2000) policy.

Die Nutztierhaltung in Deutschland hat sich in den letzten Jahrzehnten zu einem wirtschaftlich sehr erfolgreichen Sektor entwickelt. Es wurden große Fortschritte in Bezug auf die Ressourceneffizienz erzielt. Gleichzeitig gibt es erhebliche Defizite vor allem im Bereich Tierschutz, aber auch im Umweltschutz. In Kombination mit einer veränderten Einstellung zur Mensch-Tier-Beziehung führte dies zu einer verringerten gesellschaftlichen Akzeptanz der Nutztierhaltung. Vor diesem Hintergrund hält der Wissenschaftliche Beirat für Agrarpolitik beim Bundesministerium für Ernährung und Landwirtschaft (WBA) die derzeitigen Haltungsbedingungen eines Großteils der Nutztiere für nicht zukunftsfähig und hat Leitlinien und Empfehlungen für eine gesellschaftlich akzeptierte Nutztierhaltung entwickelt. Um die gesellschaftlichen Anforderungen an die Nutztierhaltung und die Realität der landwirtschaftlichen Produktion stärker in Einklang zu bringen, empfiehlt der WBA ein umfangreiches Maßnahmenbündel und zudem einen intensiven Diskurs zwischen Wirtschaft, Zivilgesellschaft und Politik unter Einbeziehung der Wissenschaft.

Multilateral trade negotiations in the WTO under the Doha Development Agenda, often called the Doha Round, were suspended at the end of July 2006 because of the failure to reach an agreement on Modalities, especially on market access and domestic support (DS) for agricultural products. Although leading WTO members have emphasised their commitment to continue negotiations, a significant delay of any conclusion seems very likely. These developments contribute to the timeliness of this World Bank publication, which is also a political input for the negotiations at a critical stage, offering analyses of negotiations and the impact of their potential conclusion based on the Framework Agreement reached in August 2004. The analyses reported are based to a large extent on the most recent state of negotiations. After a summary of key results by the editors, the book contains eleven chapters authored by different researchers. Many cross-references between chapters exist, which adds value to the collective publication of papers. Two chapters analyse the general impact of various liberalisation scenarios based on computable general equilibrium (CGE) models. Other chapters offer an overview of the development of agricultural policies, an analysis of the state of negotiations and options for Special and Differential Treatment (SDT) of developing countries, and a case study on cotton. The rest of the volume can be classified according to the three pillars of the negotiations: three chapters on market access, two on domestic support (DS) and one on export competition. The focus on market access is well chosen as this has been the most contentious issue in the negotiations, with the most complex set of parameters to negotiate and the largest effect on production and trade, a point made in the chapter by Hertel and Keeney. In light of this volume's explicit focus on developing countries, some discussion of the links between trade liberalisation, the associated positive welfare effects derived from simulation models and economic development, would have been appropriate. Such a discussion would involve aspects of domestic institutions and income distribution that are largely neglected in this volume, although available elsewhere (see e.g. Hertel and Winters, 2006 ).

The significance of standards in international agricultural trade is continuously rising. Due to their complexity, especially private industry standards are often expected to have a negative impact on agricultural export sectors in developing countries. The successful adoption of standards by a broad number of producers can be seen as a condition to limit negative socioeconomic consequences. This case study for the mango export sector in Piura, Peru, analyzes the adoption of the Eurepgap standard, based on a theoretical framework of a compliance process of three stages (information stage, decision stage, implementation stage). The empirical part is based on interviews with farmers. A comparison between certified producers and a control group identifies the mechanisms that lead to an adoption of the standard. A first major barrier to adoption is the access to information on the standard. Exporting enterprises are the most important source of information. Analysis at the decision stage shows that vertical integration is the most important factor in the adoption of the standard. A contemplation of the implementation stage shows that the costs of compliance are at 9.51 US$/ton on average or 3.8% of the product price. Factors that influence the costs of compliance are the starting point, the target level and the involvement of exporter enterprises. Consequently, the activities of exporter enterprises can be identified as the key factor for the adoption of the standard in the sector. Furthermore, the standard involves the risk of exclusion of certain producer groups.

Social dimensions of multifunctional agriculture in Europe - towards an interdisciplinary framework
2021International Journal of Agricultural Sustainability · 34 Zitationen · DOI
Agriculture is embedded in and interacts with both its ecological and social environments. Under the concept of ‘Multifunctional Agriculture’, these interactions receive attention from scientific and political communities in terms of societal functions that can be fulfilled by farms. The discourse has focused on ecological functions, while agriculture’s social contributions are frequently mentioned but not systematically addressed. Accordingly, respective empirical results remain fragmented and applied conceptual approaches barely integrated. To address this research gap, we conducted a systematic literature review on the social functions of European agriculture. Our analysis (a) disentangles different definitions and categorizations of social functions found in the literature; (b) proposes an interdisciplinary framework and categorization that eases the linkage of relevant insights from different conceptual viewpoints; and (c) paves the way for the differentiated recognition and governance of the diverse social functions potentially delivered by farms and their activities in the European context.

Abstract Perennial biomass crops (PBC) are considered a crucial feedstock for sustainable biomass supply to the bioeconomy that compete less with food production compared to traditional crops. However, large‐scale development of PBC as a means to reach greenhouse gas (GHG) mitigation targets would require not only the production on land previously not used for agriculture, but also the use of land that is currently used for agricultural production. This study aims to evaluate agricultural market impacts with biomass demand for food, feed, and PBC in four bioeconomy scenarios (“Business as usual,” “Improved relevance of bioeconomy,” “Extensive transformation to a bioeconomy,” “Extensive transformation to a bioeconomy with diet change”) to achieve a 75% GHG reduction target in the emission trading sector of the EU until 2050. We simulated bioeconomy scenarios in the energy system model TIMES‐PanEU and the agricultural sector model ESIM and conducted a sensitivity analysis considering crop yields, PBC yields, and land use options of PBC. Our results show that all bioeconomy scenarios except the one with diet change lead to increasing food prices (the average food price index increases by about 11% in the EU and 2.5%–3.0% in world markets). A combination of the transformation to a bioeconomy combined with diet change toward less animal protein in the EU is the only scenario that results in only moderately increasing food prices within the EU (+3.0%) and even falling global food prices (–6.4%). In addition, crop yield improvement and cultivation of PBC on marginal land help to reduce increases in food prices, but higher land prices are inevitable because those measures have only small effects on sparing agricultural land for PBC. For a transition to a bioeconomy that acknowledges climate mitigation targets, counter‐measures for those substantial direct and indirect impacts on agricultural markets should be taken into account.

The petroleum sector contributes substantially to the Nigerian economy; however, the potential benefits are diminished because of the existence of significant subsidies on imports of petroleum products. Subsidies on imported petroleum products are considered to be an important instrument for keeping fuel prices, and hence the cost of living, low. The costs of these subsidies, however, have risen dramatically in recent years along with increased volatility in world petroleum and petroleum product prices and increased illegal exportation of subsidized petroleum products into neighboring countries. Removing the subsidy on fuel is one of the most contentious socioeconomic policy issues in Nigeria today. In this paper, an economy-wide framework is used to identify the impact of removing the fuel subsidy on the Nigerian economy and investigate how alternative policies might be used to meet socioeconomic objectives related to fuel subsidies. The results show that although a reduction in the subsidy generally results in an increase in Nigeria’s gross domestic product, it can have a detrimental impact on household income, and in particular on poor households. Accompanying the subsidy reduction with income transfers aimed at poor households or domestic production of petroleum products can alleviate the negative impacts on household income.

Purpose – Like many countries in the developing world, Ethiopia has leased out a huge amount of land to foreign investors. However, empirical evidence on the contribution of international investments to employment generation and food security is limited. The purpose of this paper is to examine the contribution of large-scale farms to local-level food security in Bako Tibe District, Oromia Region. Design/methodology/approach – Primary data were collected from 200 randomly selected households from two purposefully selected villages in the district. Secondary data were collected from government offices and the literature. Propensity score matching was used to match households based on observable characteristics. Using the World Food Programme (WFP) approach, the food consumption score (FCS) of households was calculated. Finally, the Average Treatment effect for the Treated was determined. Findings – Findings indicate that foreign land deals increase the odds of households falling into food insecurity and that the employment opportunities are both temporal and marginal. Furthermore, these land deals result in a decline of households’ FCS and thus have a negative effect on households’ food security. Research limitations/implications – The result is based on a case study which is not generalizable to the whole of Ethiopia. Practical implications – The result implies that future endeavours should resort to substantial changes in the principles of investment as well as the design and enforcement of contracts on land transfers so that international investors can commit to objectives beyond private profit. Originality/value – It examines the effect of large-scale land transfers commonly termed as land grabbing on local food security. The paper makes an important contribution to the current policy debates regarding land grabbing in Ethiopia as research about the contribution of land deals to the food security is limited.

The inclusion of agricultural products in the current customs union is one of the potential future steps on the road to further political and economic integration between Turkey and the EU. This book examines the effects of such integration of agricultural markets on the Turkish agricultural sector as well as on consumers and the Turkish budget. Results are compared to alternative options for Turkish agricultural policy. To this aim, a detailed partial equilibrium model of the Turkish agricultural sector is developed. The complete liberalization of the agricultural sector is found to lead to significant welfare gains compared to the maintenance of current policies. It appears that including agricultural products in the customs union results in similar results with few but significant exemptions.

This paper provides policymakers with an ex-ante assessment of the implications of malaria control and elimination on household welfare across various malaria epidemiological zones. These insights assist in developing and implementing related policy measures that reduce the undesirable effects in the short run. Besides, the paper supports an economically beneficial long-term malaria control and elimination effect.

Distributional effects of CAP liberalisation on western German farm incomes: an ex-ante analysis
2013European Review of Agricultural Economics · 23 Zitationen · DOI
We measure impacts of liberalising European agriculture on farm income distribution in western Germany. Unlike previous studies, we do not treat market income and policy support as independent income sources. We jointly apply a partial equilibrium and a programming model and find that liberalisation increases inequality in relative terms though it decreases inequality in absolute terms. In particular, we analyse the relevance of taking into account policy-induced production and market responses in an ex-ante inequality analysis. We find that although their inclusion generally does not affect the direction of distributional effects, it may have considerable impact on their magnitude.

Reforming Agricultural Trade for Developing Countries is a two-volume set containing 16 chapters from different authors and an introduction from the editors. They focus on the multilateral negotiations on agricultural trade liberalisation in the World Trade Organisation (WTO). Most of the papers were first presented in May 2002 at a workshop on The Developing Countries, Agricultural Trade and the WTO, with the aim of providing input for the Doha Round negotiations, which at that time had just got underway. The first volume, subtitled Key Issues for a Pro-Development Outcome of the Doha Round, contains nine chapters. In the first four, McCalla and Nash, Josling, Sharma and Hoekman et al. offer an excellent introduction to the topic with a comprehensive overview of the state of agricultural support and negotiations in the WTO from a development perspective. These chapters largely summarise existing knowledge in 2002, and unfortunately do not take into account many substantial more recent policy changes, e.g. in the EU and the US with respect to domestic support. Hoekman et al. analyse statistically the degree to which developing countries are affected by domestic and export subsidies, based on the trade shares of products that are subject to such subsidies. They conclude that the Least Developed Countries are more affected than other developing countries on the export as well as the import side. Kaukab in Chapter 5 describes negotiating groups of developing countries in the Doha Round and reviews the factors impacting their stability and effectiveness.
